Quartz Surface Products; Institution of Investigation, Scheduling of Public Hearings, and Determination That the Investigation Is Extraordinarily Complicated

📌 ETDETA brief — importer impact summary (educational)

Brief takeaway: The ITC has opened a global safeguard investigation into imported quartz surface products, which could eventually lead to import relief measures affecting these goods.

What changed: According to the notice, the Commission instituted investigation No. TA-201-79 under section 202 of the Trade Act of 1974 to determine whether quartz surface products are being imported in increased quantities that are a substantial cause of serious injury, or threat of injury, to the domestic industry. The notice states the petition was deemed properly filed on November 17, 2025, and that the investigation is "extraordinarily complicated," with a serious injury determination expected by April 1, 2026, and a report to the President by May 18, 2026.

Who's affected: The notice names quartz surface products (QSP) as the article under investigation. Because this is a section 201 global safeguard investigation, it may be relevant to importers of QSP regardless of country of origin. Specific HTS codes are not stated in this notice.

What to review:
- Review whether your imported products may fall within the "quartz surface products" scope described in the investigation.
- Check the ITC investigation record and any scheduled public hearings for participation opportunities and scope details.
- Confirm with your broker which HTS classifications may correspond to QSP.
- Review the timeline (April 1, 2026 determination; May 18, 2026 report) for potential later duties or quotas.
